About St Arnaud Range Track
The St Arnaud Range Track begins in the eastern corner of Kerr Bay on the edge of Lake Rotoiti in St Arnaud. It ascends through red, silver and mountain beech forest before emerging above the bushline at around 1400 metres. The route offers changing landscapes from moraine terraces and forest to snow tussock, sub-alpine shrubs and alpine herb fields that bloom in late spring and early summer.
After approximately two hours the track reaches Parachute Rocks, named for a distinctive parachute-shaped gravel scree. From here a further 30 minutes leads to the ridge line, where views extend east down the Wairau Valley, north to Mt Richmond Forest Park, west toward Kahurangi National Park and south across Nelson Lakes National Park. The track returns by the same route.
Nelson Lakes National Park protects a glaciated landscape with evidence of past ice action visible in truncated spurs and small tarns. The area experiences alpine conditions, with freezing temperatures possible at any time of year. The Department of Conservation manages the track and provides safety guidance for visitors.
Getting There and Parking
St Arnaud lies 88 km from Nelson on State Highway 6 and 129 km from Picton on State Highway 63. The track starts at the eastern end of Kerr Bay near the DOC campground. Ample parking is available at the trailhead, with basic facilities and a visitor centre in St Arnaud village for last-minute information or supplies.
Route and Terrain
The track climbs steadily through forest on rooted paths before transitioning to rocky alpine sections above the bushline. Navigation requires care on uneven ground, especially in poor visibility. The full return journey typically takes 4 to 5 hours for fit walkers. Parachute Rocks provides a worthwhile turnaround point for those seeking a shorter outing with excellent views.
Safety and Preparation
Alpine weather can change rapidly, bringing rain, snow or strong winds. Carry warm waterproof clothing, sufficient water, food, a first aid kit and a map or GPS. No rubbish facilities exist on the track, so carry out all waste. Inform someone of your plans and expected return time, as mobile coverage is limited. Check current conditions and forecasts at the St Arnaud visitor centre before departing. Sandflies and wasps are seasonal hazards; use repellent and carry antihistamine if needed.
Flora, Fauna and Wildlife
Lower slopes feature large red beech with broadleaf and putaputawētā in the sub-canopy. Higher elevations transition to silver and stunted mountain beech. Above the bushline, snow tussock and alpine herbs create seasonal colour. Native birds such as bellbirds, tūī and kea may be encountered, along with the occasional New Zealand falcon. The park protects these species, and visitors should minimise disturbance.
What Visitors Often Say
Walkers describe the steady climb through beech forest as rewarding, with expanding views that make the effort worthwhile. Many highlight the dramatic outlook from Parachute Rocks and the ridge as highlights of the day.
Visitors note the track suits experienced hikers comfortable with steep sections and variable alpine weather. Several mention the value of checking conditions locally and carrying layers for temperature changes at elevation.
